Product Description

Nankarrow IsoBoard™ is a soundproof bonded magnesium oxide board made out of magnesium oxide, 15% pine wood bonded by polymeric fiber and cement. This makes for a revolutionary, waterproof, soundproof acoustic panel designed to improve impact and airborne noise transfer.
IsoBoard™ Acoustic Panels are constructed from three well established building materials – magnesium oxide, wood and cement. IsoBoard™ is a very dense product, light grey in colour and both faces have a hard smooth flat surface.  Due to adoption of a special manufacturing process, the panel acquires the strength & durability of magnesium, & the easy workability of plywood – a combination of qualities absent in any other board. Magnesium Oxide is strong & durable, & is not affected by fire, weather, termites, etc. Wood is light & strong, & is easily machinable. As the magnesium oxide particles in the board are mineralized with chemicals during the manufacturing process, so the board become termite & vermin resistant.


IsoBoard™ Plywood Gypsum Board Calcium Silicate Board MgO Board
10mm + 10mm Partition on 2″ Frame 23dB 15dB 14dB 18dB 19dB
20mm + 20mm Partition on 2″ Frame 36dB 24dB 23dB 28dB 29dB


Note: Adding one layer of Tecsound 100 between two 10mm Isoboard panels gives you an STC of 45db with a total thickness of only 25mm (1 inch). This is the preferred approach to critical soundproofing applications, such as recording studios and home theaters.

IsoBoard™ is three times as heavy as plywood, and thus has three times better soundproofing abilities. A 10mm thick panel of IsoBoard™ provides the same soundproofing as a 24mm thick plywood panel.

Application: It can be used in various places like Recording studios, Home theaters, Rehearsal rooms, Auditoriums, Dubbing rooms, Hotels, Restaurants, Voice Over (VO) Rooms, Cinemas, Generator rooms, etc.

Key Features:

  • Excellent sound attenuation,  acoustic dampening material with higher density and elasticity.
  • Non-combustible Class A Building Material
  • Excellent load-carrying capacities over spans up to 4 feet.
  • Highly moisture resistant
  • Resistant to fungus, termite/vermin, impact and general abuse.
  • Non-toxic, contains no hazardous volatiles, asbestos or formaldehyde.
  • Environmentally safe
  • Dimension accuracy down to 1/16th inch, and highly stable.
  • Installs and fabricates using standard carpentry tools and equipment.
  • Nailable for shingle applications as roof sheathing.
  • High fastener pull-out values.
  • Stronger and more rigid to allow thinner material to do the same job
  • Easier to work with using all types of hand tools and wood working equipment but also can be cut with quick score and snap faster than drywall

IsoBoard™ Panel Uses:

  • For soundproofing wall, ceiling, and floor
  • Highest levels of soundproofing
  • Same properties as plywood, seamless finish.
  • Will not rot, warp, delaminate or disintegrate
  • Suitable for use in interior and exterior applications
  • Non-combustible
  • Easy to cut and fasten
  • Air borne sound reduction varies between 30 & 37 db for the frequency range 100 – 3150 Hz according to the thickness of IsoBoard™ Panel. When used in stud partitioning, a reduction of over 60 db can be achieved with suitable construction.

Due to dense monolithic structure, installations throughout the world show that even without sealing, the cement bonded particle board suffers insignificant deterioration when exposed to extreme climatic conditions. The board can withstand any temperature from -40 to +90 deg. C.

Wood Workability

IsoBoard™ Panel can be drilled, sawn, & sanded with normal wood working tools. For bulk volumes, IsoBoard™ should be cut with Tungsten Carbide tipped circular saw & drilled with high speed steel drill bits. It can be fixed using screws & nails. Pre-drilling a hole slightly bigger than the shank would be required.

Smooth Surface

IsoBoard™ Panel is light grey in colour with a smooth finish. It can be decorated with minimum preparation. IsoBoard™ can be finished with laminates, foils, & paints using  Alkaline resisting adhesives, primers, & paints

Fire Resistance

IsoBoard™ Panel is highly fire resistant & has been classified as an incombustible material in many countries around the globe. Tested in accordance with BS 476 – Fire test on building materials & structures, Parts 6, 7 have classified it as a class ‘O’ building board with class I surface spread of flame. IsoBoard™ can be used for the construction of fire resistant building elements to satisfy the criteria of I.S.O. 834 – 1975 & I.S. 3809 – 1979 for 1/2 hour to 4 hours fire rating.

Weather Resistance

With cement constituting 62% of its composition, IsoBoard™ offers excellent resistance to weather. The board has been subjected to many cycles of soaking, freezing, & heating without any sign of disintegration. The board should generally be painted or for external applications to provide a weather seal.

Biological Properties

Due to mineralisation of particles, IsoBoard™ Panel is resistant to termite & vermin attack. It also does not support fungal growth. Untreated samples exposed to contact with ground surface for several years have no sign of rot or decay. Further, IsoBoard™ is radiologically fit for use as per BARC (Bhabha Atomic Research Center) test reports.

Our head-office is in Mumbai; however, we don’t have a showroom or physical stores. We're an online company - we distribute our products online all over India via a distributed warehousing system - we have warehouses in 8 locations. Since our products are technical and used for solving specific acoustic problems, they do not attract walk-in customers. If you want to buy our products, just place your order online or reach out to us via the contact forms.
We do not offer Cash on Delivery. Our products are extremely large and bulky - you can fit a human being into most of our boxes. As a result, one of the highest costs in running this company is the money paid to courier companies like Fedex, XPressBees, etc, which runs into crores of rupees annually. If we allowed COD and the buyer changes their mind and refuses to pay during delivery, we incur double shipping costs (a) for sending the product to the buyer + (b) for shipping the product back to our warehouses. In some cases, this may be more than the value of the product itself. For this reason, we find it impossible to offer Cash on Delivery.
We follow maximum transparency in showing you actual delivery dates at a product level. The exact delivery dates are visible on each product page, cart page, checkout page, as well as your order confirmation emails. Once your order is shipped, regular shipping updates are provided via SMS.
We supply products only. We're an ecommerce company and our focus is on importing, distributing, manufacturing, and supplying a wide range of technical isolation & acoustic products across India. For installation you can engage local contractors / carpenters. Please contact us if you need specific information on installing any product in our catalog.
We accept returns upto 30 days from the date of receipt of product. If you need to return a product, just contact your sales representative and we will arrange a reverse pickup via Fedex. Your refund will be processed within 3 days after we get it back. We charge a 15% fee for restocking the product so this is subtracted from your refund. This is waived off if you have not removed a product from it's original packing and are returning it unused.
Your order could be in several spots... our warehouse, our custom-shop manufacturing units, anticipating dispatch, with the courier on its way, or conveyed. The principal thing to check is have you had your dispatch email? If yes, at that point it's en route. You can track your order by clicking your tracking link from that email. In the event that you haven't got your dispatch email within a week of placing your order, please do contact us.
